WIRING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 245,154, dated August2, 1881,

* Application filed July 12, 1881. (ModeL) act description, referencebeing had to the accompanying drawings, making a part of thisspecification, in which- Figure l is a perspective view of awiringmaehine with ourimprovements attached. Fig.

' 2 is a front elevation of the same.

To enable others skilled in the art to make and use our invention, wewill proceed to describe the exact manner in which we have carried itout. V

Our invention has special reference to wiring the rims of large copperand brass kettles; and it consists of the combination of devices ashereinafter described and claimed.

In the drawings, A is the frame for'supportin gthe ordinarymachinery ofwirin g-machines.

The gearing for giving motion to the formers or revolving; heads is allof well-known construction.

On a lower shaft, 13, is fixed an elongated grooved hub or former, (J,and on an upper shaft, F, arranged in a line with shaft B, is a shorthub or former, D, which projects into the mouth of the kettle or canbeing wired, and is provided with a groove corresponding to thegroove inhub O. The. peculiar conformation of the lower former prevents thecrimping of the portion of the sheet metal within a short distance ofthe rim by sustaining it and pro venting the base of the can fromdropping down, the inner surface being retained in a uniform shape, andthe metal is made to fit closely to the wire. The flange d on the outeredge of hub D forces the edge of the metal-tightly around the wire anddown against the body of slot, t, in the base of the machine.

evident from our construction that the wired rim of the kettle will beset partially over the inner surface of the kettle. The wired rim beingthus set, the wire is more securely held in position than if theextension was altogether .outward, and the inner edge of the kettle isless liable to receive bruises, while the inner extension of the rimfurnishes a stop to boiling fluids, and thus lessens the liability tooverflow.

'We providethe guide E with a facing of wood or leather, the latterbeing found preferable. The friction of the kettle against a metal guidehas the effect to deposit copper on the face of the guide, which bydegrees hardens it beyond the hardness of ordinary copper, so that therim of the kettle is liable to become scratched and defaced. To overcomethis difficulty we face the metal guide with leather or other suitablesoft material, as shown in Fig. 1.

In operating our device the rim of the kettie is first upset in theusual way, so as to have the metal turned back upon itself, but leavingroom for insertioii of the wire. The open end of the kettle is thenplaced over the elongated head of the lower former and pressed upagainst the guide E, .the upper former, D, having previously been raisedby the adjusting mechanism G. The wire is then inserted under the upsetrim and the former D lowered, so as to press the metal around the wire,as will be ob vious. The formers are then rotated by any suitable meansuntil the entire rim has been wired, when the former D is again raised,as before.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. In a wiring-machine,the elongated grooved former O, in combinationwith the grooved former D, provided with the sharp flange d,substantially as and forthe purpose set forth.

2. In awiringmachinefihe elongated grooved former O and the groovedformer D, provided with the sharp flange (I, in combination with theguide E, provided with a face of suitable soft material, substantiallyas described.
